When concerned about facial sagging, how do you distinguish between lifting procedures and volume management?

Lately, I often hear that my face looks more tired than before.

I found it difficult to tell on my own whether my skin was sagging or if I had lost volume.

While looking into lifting procedures, I realized that a lack of volume might actually be the cause.

It seems like the two have different approaches, so I'm curious what criteria are used to distinguish them.

Rather than deciding on a procedure first, it would be best to accurately examine the changes in your face.
